BYRONPHELPS, OF SEATTLE, VASHINGTON, ASSIGNOR OF ONE-HALF TO THEODORE NELSON, OF CHICAGO, ILLINOIS- LOCK.

sPncrFIcA'rroN forming pari. of Letters Patent No. 631,433, eared August 22', 189e. Application filed February 4, 1899 Serial No.. 704,510. (No model.)

To all whom zt may concern.'

Be it known that I, BYRON PHELPs, a citizen of the United States, residing at Seattle, c ounty of King, State ofWashington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and Vexact description. f

My invention relates to locks; and my object is to improve the construction of the same.

In the preferred embodiment of my inven` tion shown in the drawings, Figure l represents a horizontal section through my lock. Fig-2 represents a sectionon the line 2 2 of Fig. 1 looking in the direction of the arrow.V Fig. 3 represents a section on the line 3 3 of Fig. 1 looking in the direction of the arrow, and Figs. 4 and 5 represent details.

In the above-preferred embodiment, A represents the frame of the lock, having spindlebearings B and O. The frame is obviously stationary relatively to the moving parts of the lock, and in the claims l have included the frame under the designation a relatively stationary part, although I do not mean that' the frame must necessarilybe the stationaryv part. b and c are escutcheon-plates'. This general style of lock construction, adapted tov be inserted in a notch in the stile of a door, is described and claimed in myformer application, Serial No. 698,371. VRenewed application was liledDecember 5, 189.8. Within the spindle-bearingsl is a rotatable spindle, the ends of which project from the bearings, and to these ends are. attached :knobs K M, as shown. I have designated these ends D and E.

F is a latch bolt or head pivote'dto the frame, and f is a connecting means to this bolt, preferably in the form of a yoke,'as shown in Fig. 5, having two arms to be engaged by the roll-backs, so that the bolt will be retracted by the rotation of a spindle in' either direction. f

G is a roll-back connected with the spindle to contact with the yoke and actuate the` bolt. This roll-back is preferabl'ylocate'd in and held in place by a slot g in the spindle D, as shown inY Fig. 4.

H is a finger-piece formed in this embodilnent of a rotatable cup-shaped portion h, and a cap therefor h', closing the same and preferably fixed with relation to said cup. This ment formed by a projection from knob. K.

.The cap h' is in this embodiment fixed to the lspindle-bearing; but the cup-shaped portion h is rotatable relatively to vsaid bearing. The cup portion and cap are held in place between projection la and an abutment formed in this embodiment by shoulder h2. I have provided a means to lock the spindle from rotation and adapted to be operated by the linger-piece, which isv located on t-he side of said lock opposite said'end D. e is a slot in'and inv this embodiment a hole through endE of the spindle, and c is a hole registering therewith in bearing O.

h3 is a dog pivoted to cap h' by the pin h, and hg is a spring acting on a projection from said dog, as shown in Fig. 2, to turn the same on its pivot. This dog has a lug h5, adapted to V.pass from the hole c in the spindle-bearing into the hole e in the spindle to lock the spindle from rotation. h6 is a pin carried by the rotatable part ofthe finger-piece. 717 and h8 are depressions in vthe face of said dog, forming cam-faces,the bottoms of which depressions are atv different radial distances from theV center of the nger-piece, so that when saidpin h6 is moved from the one to the other the dog will-be turned, and consequently the lug h5 will be moved` laterally of said spindle and into or out of engagement therewith. A Said depressions also form a locking means for said finger-piece, as the pin will not ride out of one into the other without slight pressure.

L is a slot preferably in the spindle and preferably wider than slot g, and in this IOO getherbyscrmis, as shown. Contained within this knob and fixed relativelythercto, so as to be movable therewith, is a preferably pin tumbler-lock on, havingan innerpartrotatable relative to the lock-easing, suoli as a key-barrel, as is common to this class of locks. This construction is broadly claimed in my application, Serial No.(5)9,Jl, tiled December 2l, 1593, and I do not therefore consider it necesary to more particularly describe or illustrate the same herein. m is a reduced portion of this pin tumbler-lock casing, and m2 is a ring into which said reduced portion tits, and mais a depression in the knob in which said ring may be located. m4 is a projection on the end of the rotatable key-barrel, over which fits a hollowed cap N. The projection and cap construction is broadly claimed in my said application Serial No. 699,801. This cap has a hole therein preferably angular, and passed through and litting this hole is a preferably angular rod tt, having a head 01.' thereon contained within said hollowed cap. The cap is fixed to the projection m4 by a pin n2, as shown. This rod, which I designate a key-rod, passes inward from the cap N loosely through a round hole in roll-back G, as shown in Fig. 5, so that said roll-back will not be actuated thereby when said rod is rotated. This rod then connects directly with roll-back L', passing into a hole in said roll-back, which tits said rod, so that when said rod is rotated said roll-back L will be moved to draw back the bolt.

When in this embodiment either knob K or knob M is rotated, the roll-back G will be moved and will contact with yoke fand draw back the bolt. Ihen the finger-piece is rotated from the position shown in Fig. 2 in full lines to that shown in dotted lilies, the pin h6 will drop into the depression hs, and the lug h5 will enter the hole e in the shaft E and lock the spindle from rotation. rlhe knob M is thus locked from rotation, and as said knob is intended to be upon the outer side of the door the door is thus securely locked from entrance from this side. Akey, however, may be inserted in the key-barrel of the pin tumbler-lock, as is usual in such locks, and the key-barrel rotated, while the knob M and spindle still remain fixed. This rotation of the key-barrel will also rotate keyrod fn., and consequently roll-back L', throwing back the bolt, and yet the spindle relnains locked.

It will be obvious that very many changes may be made in the construction herein disclosed without departing from the spirit of my invention.

Vhat I claim is- 1. In a lock in combination, latch mechanism embracing a latch bolt or head, a rotatable spindle, bolt-actuating means connecting with said spindle and adapted to be operated to retract said bolt by the rotation of said spindle, a knob on said spindle, mechanism embracingadetent outside said spindle adapted to move laterally of said spindle to lock said spindle from rotation and operative from the side of said lock opposite. said knob, and key-operated means to move said bolt independently of said locked spindle operative from the same side of said lock as said knob.
